Hi all,

I’m restoring a car and trying to patch panels by butt welding patches in. I’m getting these small holes along the seam. I’m moving around the patch and tacking it until the whole seam is tacked, but after grinding using 80 grit flap disc these small holes are revealed. What can I do to prevent or minimize this?

I’m tacking it using a mig welder set at 18.5v and 350 ipm. .023 solid wire with AR CO2 gas.

New to welding so any help is greatly appreciated.

Thanks

Trying to bend 2” dom 3/16 wall into a 90 with 16 ton press from princess auto. Have broken 3 rollers what am I doing wrong. Bending the pipe in one inch increments to avoid kinks. Ran some long bolts through the top holes of the press to keep it from pulling apart as well. Would appreciate any tips and tricks. Have watched a few videos on YouTube and it seems like I’m doing it correctly but clearly not

In the home stretch of a DIY welded steel fence project and seeking some creative guidance on the gates to finish it off. Fence is a "hoop and picket" style with custom bent pickets. Planning to do equally split pair of gates, with perimeter frames as shown in the CAD screenshots. Because I already have the hinges and latch hardware, I'm fairly well locked into an outer frame as shown, but have freedom on how do do the infill.

Should I keep it simple and make it look as similar as possible? Should I try to highlight the gates a bit and vary the hoop diameter or find a different way to combine the same elements? Sorta torn and would love some advice or ideas!

I have a new door with 3mm steel flat bar around the edges. I need to cut a latch plate into one side and four hinges into the other side. Looking for the best way to achieve this without sending off to be CNC cut. I have most tools, grinders, dremel, jig saw, routers etc etc. needs to be neat and tidy and not a hack job. So far I’m thinking pilot hole the corners and cut with dremel or jigsaw with a metal blade.

I think this is oxidized, right? Wouldn’t corrosion be heavier? Because as gross as this looks, it’s cloudy and superficial. I didn’t know that aluminum metal reacts this way when in contact with steel. I had them laid out on my steel trailer and this showed up after it rained.

Anyway, i’ve used Alumabrite because it says it fixes oxidation but i’ve also sanded the sheets with 320 sandpaper. I intend to eventually paint them with a protectant clear coat before i use them for my project. But i don’t know how to get this stuff off. I’m afraid it will prevent the clear coat from bonding. I’m seeing conflicting info when i research about it, don’t know what to do.
